LOONI FOR TUFTED OR PILE FABRICS.

SPECIFICATION forming part of Letters Patent No. 769,851, datedSeptember 13, 1904;,

Application filed October 3, 1903.

To all whom it nuty concern.-

Be it known that I, CARL VORWERK, a subject of the German Emperor,residing at Barmen, in the Rhine Province, Prussia, Ger many, haveinvented certain new and useful Improvements in Looms for Tufted or PileFabrics, of which the following is a specification accompanied bydrawings.

This invention relates particularly to looms for weaving Jacquard-Axminster carpets; and

the object of the invention is to improve upon the construction andoperation of such looms and improve the appearance of the fabric.

Further objects of the invention will hereinafter appear; and to theseends the invention consists of apparatus for carrying out the aboveobjects embodying the features of construction, combinations ofelements, and arrangement of parts having the general mode of operationsubstantially as hereinafter fully described and claimed in thisspecification and shown in the accompanying drawings, in which- Figure 1is an end elevation of a portion of the loom from the rear, showing thereeds and warp-threads in the spaces of the tablecomb, which is shownbroken away at each side. Fig. 2 is a side elevation of the portion ofthe loom shown in Fig. 1, partly in section. Fig. 3 is a plan viewshowing the central portion ofthe table-comb with the reeds and Fig. Ais a sectional front elewarp-threads. vation showing three carpetbreadths oined which have been woven by means of a tablecomb having therecesses completely sym the pile is formed of tufts which are severedfrom the pile-yarns in jacquard-controlled carriers and brought down bygrippers or nippers resembling a gooseneck and beak to a table-combsupporting the fell of the cloth and guiding the warp-threads. Then thetufts perfect in certain respects.

are looped around the weft and bound into the cloth when the weft isbeaten up by the lay.

The table-comb heretofore employed is im- Sufficient room has not beenprovided between the teeth of the comb to accommodate both thewarpthreads and the reeds, so that the threads are crushed and weakened,and it is consequently difiicult to raise the tufts steadily anduniformly without further means. In order to obviate thesedisadvantages, the comb is con structed in accordance with thisinvention as hereinafter to be described.

Referring to the drawings, A represents the comb; B, the lay; C, thereeds. The warp threads E are represented passing through the aperturesof the reeds (1. As shown in the drawings, the reeds C are adapted toenter between the teeth F of the comb. The tuftsGr are shown in Fig. 2on the table-comb A looped into the fabric.

According to this invention the teeth F of the table-comb A, Figs. 1, 2,and 3, are each provided at one side with recesses H, so' arranged andof such shape and width that the warp-threads E are provided withsufficient room to lie therein, while at the same time protection isafforded from the crushing action of the reeds C when the lay is beatingup the weft. Thus the warp-threads E are kept from being damaged, andthe tufts G are turned up around the weft without further means into thevertical position,in which they are maintained by the projections'I onthe teeth of the comb until they are secured by a further shoot of weft.It is, however, necessary to symmetrically dispose the recesses H in theteeth, so if the teeth F at the left half of the comb are provided withthe recesses H, say, on the right side, as at K, Fig. 3, the teeth onthe other half of the comb are provided with recesses at the left side,as at J, facing toward those on the teeth at the left half of the comb,for if this symmetrical arrangement of the recesses H is not providedthe goods would turn out somewhat conical, one edge becoming larger thanthe other, so that the sewing of two breadths would be diflicult ornearly impossible; but according to the arrangement described ofcomplete symmetry of the disposition of the recesses H the pile L, Fig.4, reflects the light somewhat differently in the left and righthalves,which is an inconvenience in all cases of weaving piece goodsintended to be sewed breadth by breadth together, for just at the joinedsel- Vages a change of the reflection of light takes place, whereby theseams become more distinctly defined, as illustrated in Fig. 4:, showingthree breadths sewed together. In order to prevent this reflection oflight, whereby the seams become more sharply defined, I change theposition of the line where the reflection changes from the selvage to aplace in the fabric somewhat distant from the selvage, and for thisreason and in order to accomplish this end I do not dispose all of therecesses H in one half of the comb opposite to those in the other halfof the comb, but only up to a few recesses next to the selvage, which Iarrange at the same side as those in the first half. This arrangement isillustrated in Fig. 5. The table-comb is provided with the recesses H atthe right side of the teeth for the portions 0 and P of the comb, whilein the remaining intermediate portion Q, of the comb they are at theleft-hand side of the teeth. In consequence thereof the pile of part P,Fig. 6, near the right selvage will show the same inclination as thepile of part 0, so that if such fabrics are sewed breadth by breadthtogether there will be no contrast in the pile at the joined selvages;but these will be covered level] y and be almost invisible. Obviouslysome features of this invention may be used without others, and theinvention may be embodied in widely-varying forms.

Therefore, without limiting the invention to the construction shown anddescribed nor enumerating equivalents, I claim, and desire to obtain byLetters Patent, the following:

1. A table-comb,having teeth provided with recesses of such shape, widthand position that sufficient space is afforded therein for thewarp-threads when the reeds enter the comb, and of such disposition thatthe teeth of one half of the comb and a few teeth next to the end of theother half have the recesses at the same side, while the interveningteeth are provided with recesses at the opposite side of the teeth, forsubstantially the purposes set forth.

2. A table-comb,having teeth provided with recesses of such shape, widthand position that space is aflorded therein for the warp-threads whenthe reeds enter the comb, for substantially the purposes set forth.

3. A tablecomb,having teeth provided with projections at the upper sideand recesses at the sides of the teeth, for substantially the purposesset forth.

4. A tablecomb,having teeth provided with projections at the upper sideand with recesses at the sides ofthe teeth, these recesses being all atone side of the teeth on one half of the comb, and on the other half ofthe comb all at the other side of the teeth, for substantially thepurposes set forth.

5. A table-comb, having teeth provided with upward projections andrecesses in the sides of the teeth, said recesses being so disposed thatthe teeth on one half of the comb and a few teeth at the end of theother half have the recesses on the same side of the teeth, theintervening teeth being provided with recesses at the opposite side ofthe teeth, for substan tially the purposes set forth.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.

CARL VORWERK.
